You have a few choices to consider when it's time to put new insulation in your attic. Some types of insulation work better than others, but they cost more too. You'll examine several factors when deciding on the best type of insulation for your home. Here are some things to think about.

Cost

If your budget is the deciding factor, then fiberglass batt insulation could be the best choice. Although it is more affordable, you'll still have quality insulation as long as you choose the correct thickness of the insulation and install it properly. Fiberglass batt or blanket insulation has been used for decades and was once the insulation of choice, so it has a long history of insulating homes. It is a good option when you don't want to spend too much money.

Installation

If you're looking for a DIY option, then you could choose fiberglass, foam boards, or blown-in insulation. Fiberglass batt insulation is the easiest to install since all you have to do is unroll it. Foam boards are more difficult to install. They require cutting the rigid foam boards to the fit and then installing them according to code. This entails leaving enough venting space, sealing the boards, and covering the boards with a barrier.

Even then, additional insulation such as fiberglass blankets may need to be installed too. Blown-in insulation is easy to install, but you'll need to rent equipment to do it. With this type of insulation, you blow small bits of cellulose or fiberglass into the attic until the floor is covered to the right depth depending on the amount of insulation you want.

Benefits

Even though spray foam costs more and it is best to have it applied by a professional, it has the most benefits when compared to other types of insulation. You might be able to apply spray foam as a DIY project, but it is difficult to work with since it expands rapidly and dries in place. You'll also need to wear protective equipment to stay safe. Hiring a professional is often best, so you get quality results.

When the foam is applied in the right way, it forms a continuous barrier against air leaks and moisture. It seals cracks as it expands, and since it adheres to the wall and hardens as it dries, it also provides additional structural support to your attic. Spray foam resists moisture, mold, and insect damage. It doesn't interest attic invaders such as rodents or raccoons since it isn't a source of food or nesting material. Plus, spray foam provides superior insulation to your attic since it seals leaks and doesn't deteriorate through compression like batt and blown in insulation can.

No matter what type of insulation you choose, putting in new insulating material and sealing air leaks as you go can make a big difference in your comfort and utility bill, so it is worth the investment, especially if your current insulation is old and ineffective.
